Ответ:
m = 25 [kg]
Explanation:
Para resolver este tipo de problemas debemos de utilizar la segunda ley de Newton, la cual nos dice que la fuerza es igual al producto de la masa por la aceleracion.
ΣF = m*a
Donde:
F = fuerza = 70 [N] (units of Newtons)
m = masa [kg]
a = aceleracion = 2.8 [m/s²]
Ahora despejando la masa de la anterior ecuacion.
